Summary: There was a thread inside his mind. Every time that imposter who looked just like him touched Deku, it was stretched tauter and tauter until finally, it snaps. When it does, well, there's no holding back for him. He's going to show Deku just who he belongs to. 

This is a commission for anon! 

-

He wasn’t going to do anything…until Deku walked directly into his path. Coming to a dead halt, the gnawing rage that had been eating away at his stomach for hours now intensifying at the sight of Deku’s face, Bakugo stared blankly down at him. Surprisingly, his first instinct wasn’t to send him flying with a well-aimed explosion. His hand didn’t so much as twist. By that point, he was so far beyond that kind of reaction that it didn’t even cross his mind. No, this rage…it was quiet, cold – an agonizing shard of ice that was slowly digging itself deeper and deeper into his stomach. Grinning sheepishly – fucker hadn’t been paying attention to where he was going, shocking – Deku didn’t move out of the way. Instead, he tilted his head back to look up at him with those big, stupid eyes and said in a light, friendly voice, “You were incredible in training today, Kacchan.”

“Hah?” Bakugo replied coldly, the corners of his lips curling into a snarl, “Like you could have seen anything around the bastard. Did you even do anything or did you spend the entire time trying to keep him from shoving his tongue down your throat?”

An intense flush of red flooded into Deku’s face. Eyes widening, he gawked stupidly at Bakugo for a moment before quickly looking away, blinking rapidly. Wringing his hands, Deku sputtered, “I-It’s not like that…we just…we were…”

“Fucking in the weight room.” Bakugo said flatly. 

All the color drained from Deku’s face than came rushing back so quickly, it was amazing that his head didn’t explode into a puff of steam. With an expression that clearly screamed ‘oh no’ on his brightly flushed face, Deku very slowly, very shakily turned back to look up at him, “Y-Y-You saw…us?”

“Yeah.” In contrast to Deku, he was shockingly calm. Or well, calm on the outside. Inside was a different matter. It might’ve not been showing on his face but he was dangerously close to losing his goddamn shit. Fucker didn’t even try to convince him otherwise, not that he trying would have made it any better. No, he just outright admitted it. Least he had the decency to look embarrassed. “Couldn’t even wait to get back to your dorm, huh? Never would have thought that innocent little Deku would be so much of a slut, he’d spread his legs after only knowing a guy for a couple of days.”

Deku visibly bristled. Brows lowering, his mouth set into a thin line, Deku snapped, “That’s unfair! It’s because he’s-!”

“He’s what?” Bakugo asked sharply, “Someone you know you can fuck without consequences?”

“No, that’s not-!”

“It’s not? So you are saying you’d just fuck anyone as long as they show you enough attention, huh?” Bakugo’s lips stretched into a sneering smirk, “You really are a shameless whore.”

This…it wasn’t making him feel any better. It was only making the nauseous tightness in his belly even worse. Every word that came out of his mouth did nothing to sate this gnawing rage. Watching Deku get more and more distressed as he threw unnecessary insults at him wasn’t helping either. If anything, he’d argue that it was just making it worse. He was furious at Deku but this…this wasn’t what he wanted. Bakugo’s hands clenched into tight fists. Why was he so upset? Why did he care who Deku fucked? Did it bother him because the scum was fucking someone who was, essentially, a carbon copy of him? Some differences, of course – fucker did come from an alternate timeline (supposedly) but that didn’t change the fact that a version of him had been practically glued to Deku’s side since he first showed up a few days ago and now, said fucker had last been seen fucking Deku senseless in the weight room. Bakugo’s blunt nails dug into his palm. Deku’s loud, breathy moans were still ringing in his ears. He could still fucking hear it…Deku moaning out his name as he was being fucked by an inferior copy. His pulse throbbed in his temple. A sickening drip of cold rolled down into his already lurching stomach. Why was he so pissed? Why the fuck did he care? Nothing made sense. It not making sense was only making him even more pissed off! 

“Deku.” A low, raspy voice rudely yanked him back to reality. 

Bakugo’s head jerked up. His teeth clenched together. Red burned around the corners of his vision. Walking around the corner was the imposter himself: a Bakugo Katsuki from another world. The sweat on the palm of his hand crackled as he stepped closer to Deku, reaching out to rest one large, scarred hand on his shoulder. If it weren’t for his clothes or the twitching, fluffy ears sprouting out of a thick poof of ash blond hair, they could easily be mistaken for twins. There was practically no difference between them…physically speaking of course. When it came to personality, this one was a little more level headed, serious and reserved, while also being stupidly affectionate towards Deku. The moment he stepped foot into their world, he’d been all over Deku. That alone had been enough to infuriate him but knowing this bastard had fucked him as well…that went into a whole another ballpark of seething rage. 

“Kacchan…” Deku said softly, turning away from Bakugo. 

He hadn’t realized it before but there was a thread inside of his mind. Every time that bastard touched Deku, every time he called his name, every time he looked at him with that stupid fucking gaze that was so sickeningly warm and loving, it was pulled tauter until the very center of the thread was barely visible. The moment Deku’s gaze slipped away from him to stare up into that imposter, it snapped. He was moving before he realized it – one hand lashing out to grab Deku’s elbow. Shaking violently, Bakugo turned sharply on his heel and stomped away, dragging a sputtering Deku behind him. If that fucker called after them, he didn’t hear it. All he could hear was the roaring pound of blood in his ears. The trip up to his dorm was a blur. He could feel Deku tugging on his hold but his struggling felt half-hearted, like he wasn’t really trying to get away. Bakugo kept his elbow in a vice grip, regardless. Even if he wanted to be more gentle, his body and mind were on autopilot. He bulldozed his way towards his dorm, hardly taking notice of his surroundings. 

The door wasn’t locked but he kicked it open anyway to get in quicker. Bakugo shoved Deku inside, quickly following in after him and slamming the door shut behind them. The moment the lock clicked into place, he was surging forward, grabbing a handful of Deku’s shirt. Dragging him over to the bed, he threw him face down on top of it. The springs squeaked underneath Deku’s weight. Before the scum had time to react, Bakugo slammed a hand down on the back of his neck, pinning him down. He…he had expected Deku to struggle more than this but he was barely putting up a fight. Panting shallowly, sweat beading on his forehead, Bakugo let his gaze roam over Deku’s body. For the first time, he asked himself, very explicitly, just what in the fuck he thought he was doing. The answer came to him with startling clarity. Swallowing hard against the dryness in his throat, Bakugo reached down with his other hand to grab the hem of Deku’s shorts. He yanked them down, exposing Deku’s plump, plush ass. A scalding bolt of heat rushed down to his crotch. He went from half-hard to a near painful erection that nearly tore straight through his jeans. A jolt visibly wracked Deku’s body. Mouth hanging open, he craned his head around to gawk up at him. There was an adorable flush of red across his freckled cheeks. Exhaling slowly, a throb of dizziness making him sway, Bakugo stared down into that stupidly cute face for a moment then dipped down to press a soft kiss to Deku’s temple. As he pulled back, he got a whiff of the smell of his hair. It smelled so fucking good, he couldn’t resist pressing his face into the fluffy locks. 

“K-K-Kacchan, what’re you…?” 

“You let that bastard touch you.” Bakugo said, his voice calm and even, despite the tempest of wild heat raging inside him. 

“Huh? Kacchan…what…”

“I couldn’t figure it out…why it pissed me off so much to see that fucker touching you, fucking you but I think I get it now.” Bakugo straightened up, pushing sweat soaked hair away from his face. The inside of his dorm was sweltering, though he couldn’t tell if that heat was coming from outside or in. He quickly stripped off his shirt, tossing it aside without a second glance. Staring Deku right in the eye, his hands went to his trousers next, yanking everything open without caring if it ripped and shoving it down, letting his rigid, sopping wet cock bounce free. Deku’s eyes immediately flickered down to stare at his length. A lazy roll of heat sizzled up his spine. It might’ve just been his imagination but…there was a spark of blatant, naked want in Deku’s eyes. Bakugo stepped in close once more, curling one hand around the curve of Deku’s waist. The touch seemed to jerk Deku out of his stupor. Those big, wide eyes jumped back up to meet his gaze once more. He still looked…hesitant but there was no panic, no alarm. 

“Ka-“ Deku started softly. 

“I don’t like,” Bakugo said, his voice low and rough, “other people touching what belongs to me.”

Deku’s eyes widened. He inhaled sharply. The color in his cheeks darkened even further, “K…Kacchan…”

A squeak jumped out of Deku’s mouth when Bakugo took hold of one of his soft, marshmallowy asscheeks. His fingers sunk into the warm flesh in a way that he never would have thought could feel so good. Despite knowing what he was going to find, Bakugo was right back to being enraged the moment he spread him open to find his hole still wet. Gritting his teeth together, he pressed the tips of his fingers against the puckered opening, swirled them around a couple of times – thoroughly enjoying how Deku moaned and squirmed – then, without warning, shoved in two fingers. Deku moaned loudly, his hips arching up off the bed. Unsurprisingly, his insides were soft and stretchy – it took no pressure at all to get his fingers in all the way. Rage bubbled up his throat, ending up in his mouth as a foul taste. That bastard…he was going to kill him for daring to touch his Deku! Firstly, he had something more important to do: erasing that fucker’s touch completely from Deku’s mind. He was still royally pissed that Deku would let himself be fucked by him but knew he’d probably feel better after showing him that he was far superior. By the time he was done with him, he was going to understand that he belonged to him…that there was no one else who could make him feel as good as he could. 

“Kacchan…” Deku moaned throatily, pushing his butt back against Bakugo’s head. With a throb of heat, Bakugo realized that was way sexier than how he’d said it while being fucked by that imposter. Already on the right track – now to get to the main event. 

Slipping his fingers free from Deku’s hole, a slight grin tugging at the corners of his lips when Deku moaned in obvious disappointment, Bakugo wrapped a hand around the base of his cock. Just how fucking turned on he was already was more than a little annoying. Now was the time to be showing off his stamina, not how quickly he could cum. Clenching his teeth together, sweat rolling into his eyes, Bakugo lead the head of his cock to Deku’s drenched entrance. Deku gasped loudly, a shudder rolling through his body. A blast of erratic pleasure radiated out from the base of his belly. He wasn’t even inside yet but the sensation of Deku’s soft skin pressed to the head of his dick felt so good. Sucking in a deep breath, determined to hold off on cumming for as long as he could, Bakugo leaned down to press a kiss to the back of Deku’s neck. Stretching his mouth open wide, he bit down on the stretch of skin he’d just kissed. Deku shivered underneath him. His scent was even stronger now – the scent of his hair, sweat and soap. It made his head spin. He sank his teeth into Deku’s skin, pressing with enough strength to leave a clear, red mark. 

Warm, calloused fingertips brushed across the back of his head before lightly curling into his hair. Deku let out a short, shuddery breath, “K-Kacchan…please…”

“What, you wanna get done here quicker so you can go back and fuck him? I’m not enough for you, Deku?”

“Imagined he was you.” Deku said softly. “Before…I imagined he was you.”

“…huh?”

“I…Ka…Kacchan, it’s always been you. My eyes have always been on just you but I thought it would never be possible…that you would never look at me the same why I look at you. When the other Kacchan appeared and started acting so…lovey dovey, I…I caved. When he started touching me like that, I nearly pushed him away but…he is you, just a different you and I…I wanted so badly to be held by you that I couldn’t resist. The entire time, I was imaging he was you. I wanted it to be you, I couldn’t stop thinking about how much I wanted it to be you.” 

Blinking rapidly, Bakugo stared down at him silently for a few moments then sighed heavily. Dropping his weight down on top of Deku, he curled his arms around him, squeezing him tightly to his chest. This…this fucking moron. He was going to kill him for putting him through so much emotional distress for no good reason. Clicking his tongue in annoyance, hating that the imposter bastard got to taste Deku first just because of some stupid miscommunication, Bakugo grabbed hold of Deku’s waist once more, braced himself then slammed forward, driving his cock deep into Deku’s hot, tight ass. A loud squeal burst out from Deku’s gasping mouth. Shuddering violently underneath him, his fingers curling into the blanket, his hips arched up off the bed. The spasming walls of his ass clamped down hard around him, sucking him in even deeper. Panting heavily, electric shocks of pleasure rushing out from where his cock was being milked by Deku’s ass, Bakugo tightened his grip and started to move, roughly pumping his hips in hard, erratic thrusts. The determination to not cum right away pretty much flew straight out the window the moment he was encased in that incredible heat. 

Laughing huskily, a wide grin spread across his flushed face, Bakugo rasped, “Does it feel good, Deku? Huh? Your hole is squeezing me so tightly – it must feel incredible, huh?”

“Good!” Deku wailed, “Kacchan! Kacchan! Feels good! Your cock feels so good!”

“Who’s is better, mine or his?”

“Yours!” Deku cried without hesitation, “Yours! Yours! Yours feels so good! More! Kacchan! Kacchan! More! More!”

Rearing one hand back, Bakugo brought it sailing down onto the plump curve of Deku’s ass, earning himself an incredible, gasping moan, “Don’t ever let any other guy touch you again, get me?”

“Yes-! Kacchan! Close…I’m-!”

“Me too.” Bakugo laughed again. He considered their positioning for a moment then grabbed hold of Deku’s thigh and rolled him over onto his back so he could see that stupidly adorable face when he came. It was more than worth that little bit of hassle right as they were both about to cum. Deku’s face was flushed and hazy. Bright eyes, blazing with want and heat, stared dizzily up at him. It seemed to take Deku a couple of moments to realize that, with this change of position, he was now looking Bakugo right in the eye. When it finally dawned on him, his eyes widened. Squeaking, he covered his face with his arms. Another laugh bubbled out of him. Fuck…this piece of shit was so unbearably cute. Why…why had he waited so long to do this? Why did it take him this long to realize that this adorable fucker belonged to him? If he had realized it sooner, that imposter bastard never would have been able to touch him. Giving his head a slight shake – couldn’t change that now, all he could go was erase all traces of that asshole from Deku’s memory – Bakugo grabbed hold of his wrists, gently but firmly tugging his arms away so he could see that obnoxiously cute face. 

“Don’t hide from me.” He rasped, slowly leaning down, bringing their faces closer and closer until their lips were brushing together. Deku gasped softly. There was a moment of stillness then Deku was surging up, catching Bakugo off guard. Moaning low in his throat, Deku hungrily kissed him. Bakugo recovered quickly, cupping the sides of Deku’s face, deepening the kiss even further. Fuck…he tasted so good. His tongue was so sweet and soft. His lips felt incredible on his own. Had that imposter bastard stolen Deku’s first kiss as well? Whatever – he’d kiss him so much, he’d completely forget how it felt to kiss that bastard! 

Pulling away from the kiss with a sharp gasp, Deku panted, “Ka-Kacchan, cum-! Cumming!”

Grabbing hold of his jaw, Bakugo wrenched him back into another kiss. He slammed forward, completely sheathing himself inside of Deku’s hole. A shudder rippled through his body. The immense bubble of pleasure and heat that’d been steadily growing in the pit of his belly burst, sending out a flood of ecstasy that immediately overwhelmed his nerves. His cock swelled up even bigger than a flood of jizz was gushing into him. Underneath him, Deku let out a loud, wailing moan. His hole tightened even further around him, squeezing him as though it was trying to milk out every last drop. Hot, sticky fluid splattered all over their chests and stomach, creating a mess between them. A swell of triumphant victory swelled up in his chest. There was the first time…he was already well on his way to making Deku forget all about that imposter bastard. 

Slipping back with a harsh breath, Bakugo made quick work of getting Deku undressed, throwing aside his soiled clothes without a second look. Panting heavily, his gaze dazed, his mouth hanging open, a line of drool dribbling down his chin, Deku reached out to him with one shaky hand. Smiling teasingly, Bakugo took it into his own, bringing it to his lips to press a kiss to the scarred knuckles. He was still pissed and would probably be for a long time but the perfect way to sate this gnawing anger was to fully indulge himself in his adorable Deku. 

Well, and also beat the living shit out of that bastard imposter. That too.
